What is thermal pollution and what harm does it do?

Thermal pollution is the raising of the temperature of a water body by discharging hot water into it, usually from a power station or a factory. Warm water holds less dissolved oxygen, so fish and other aquatic organisms suffocate, and the change of temperature disturbs breeding and kills species that cannot tolerate it.

Explanation

Cooling towers and cooling ponds reduce it by cooling the water before it is returned.
